Odd Piece of Coaxial Cable

FWIW, there are several projects in the ARRL pubs, mostly for RDF, that
use a short piece of coax exactly as described as a loop.
I've seen some in books and on the 'net. Years ago, I did a one-week job on
a Coast Guard cutter and I got to see some HF loop antennas that are
standard issue for cutters. I do not recall with certainty whether they
were transmit or receive or both, but I think they were both, but not at the
same time, as certain USN fanwire antennas are.
HRO in San Diego usually has at least one HF loop on display.
